Watersheds, Groundwater, and Drinking Water

This is an invaluable aid to help you understand and assess water supplies and to define and manage protection areas for water sources. The chapters in Part 1 cover such fundamentals as watershed hydrology, groundwater hydrology, water quality, and water contamination. Chapters in Part 2 describe tools and background information that are helpful when assessing and protecting individual water sources. While written with the water source needs of Californians in mind, much of the basic information in the guide is applicable to other states as well.
